To all whom it may concern.-

Be it known' that we, Jamie W. Gem

SMITH and ORVEL E. GRAVES, citizens of the United- States, residing,respectively, at Rossville', Hamilton County, Tennessee, and Lafayette,in the county of Walker and State of Georgia, have invented certain newand useful Improvements in Controls for Tractor-DrivenPlows, of whichthe follow- 1 ing is a specification.

This invention relates to an attachment for farm tractors, particularlyof the Fordson type, and has for its object to provide novel and simplemechanism for raising and 1 lowerin and for otherwise adjusting andcontrolhng the lplows which are operated by said tractors. particularobject is to provide novel manually operablemeans for adjusting andsetting the plow for deep or shallow plowing, while the tractor is inmotion. A further object is to provide means for steadying the plow, forreventing wobbling and swaying of the ow laterally, during the plowingoperations, and

for holding the plow rigid to the. rear truck when the tractor is bemgturned. And a further and general object is to provide a mechanism bywhich the draft of the cultivating parts may 'be lightened, therebysaving fuel and reducing wear and tear of the tractor and related parts.

We attain these objects by the means set forth in the detaileddescription which follows, and as illustrated by the accompanyingdrawings, in which- Figure 1 is a top-plan view of the tractor,

to which our improvement is applied. Fig. 2 is a side elevation of thesame; showing by full and dotted lines the manner of effecting certainadjustments of the plow and its supports. Fig. 3 is a rear-end elevationof the machine. Fig. 4 is a fragmentary vertical cross-section, taken online H of Fig. 2; showing the means for attaching and supporting certainparts of the controlling mechanism. Fig. 5 is a similar view, taken online 5-5 of Fig. 2. And Fig. 6 is a view of the beam-supporting clevis,taken in the direction of the arrows 6-6 in Fig. 2.

In the drawings, 2 represents generally a Fordson tractor; 3 is themotor, by which the tractor'is driven; 3' is the crank-case; 4 is thetransmission housing, and 5 is the steering-wheel. 6 represents thefront truck is usually including the axle 6'; 7 is the rear truckincludmg the housing 7 for the differential and rear axle; 7 is thedraw-bar cap, and 8 is. the drivers seat. j

The reference numeral 9 represents a common plow, such as is usuallyemployed in connectlon with farm tractors of the class, for breaking theground, 5111(1'9" is the beam which supports and draws the plow. Thebeam 9', 'as shown in the drawings, curves upwardly and laterally andforwardly from the plow 9, and its free end pivotally secured to theaxle 6', between the adjacent front wheel and the radiator 3. tionedbetween the front and rear wheels, at the right-hand side of thetractor, and during the plowing operations, the plow 9 tra1ls, or isdragged along, and by reason of the aforesaid pivotal connection of thebeam 9 with the front axle 6', the plow tends to substantially followthe line of travel of the tractor. Heretofore, the plows, as 9, have hadno other connections with the tractor than as described, and bein freeto wobble and sway from side to side, as wellas to teeter and vibratevertically, because of the lack of suitable controlling and steadyingmeans, the work of the older plows has been more or less irregular andunsatisfactory. The present invention'h-as for its particular object toprovide a novel and simple mechanism that efi'ectually overcomes thesaid difiiculties and troubles, which will now be described in detail:

The reference numeral 10 represents a standard, which is positionedforwardly of the drivers seat, preferably between the plow 9 and thecrank-case, and is rigidly secured to a bracket 10, by bolts 10, thesaid bracket being conveniently secured to The plow 9 'is usuallyposithe forward end of the transmission housing 4. The media] portion ofthe standard 10 is preferably tied to the motor casing, by a stiff brace10 (see Fig. 4). Near the top-end of the standard 10 is mounted aquadrant or circular rack 11, having a series of peripheral notches 11,which-are eng by a latch 12 carried by a hand-lever 12 (see Fig. 1), forholding the lever in different positions. The lever 12 is pivoted to thestandard 10 concentric to the rack 11, by a bolt 12. The forward end 12*of the lever 12 is pivoted by a bolt 12 to the upaged r end of alink 13,the lower end of said liiik being pivoted to the beam 9' by a bolt 9.The said lower end is provlded with a number of perforations 13 forrendering the link adjustable relatively to the beam. The end 12 of thelever12 also connects by the bolt 12 with the upper end of a second link14 which is arranged for adjustment, the lower end of the latter linkbein pivotally connected to a lug 9 carried y the beam 9' (see Figs. 1,4 and 5). By this construction and arrangement the rocking of thehand-lever 12 on the ivot 12 as shown by the full and dotted ines in Fi2, correspondingly raises and lowers the Tow 9 and the beam 9', as shownat the ttom of Fig. 2. The portion of the beam adjacent the lug 9 isyieldably tied to the transmission housing 4, by means of a short link14, as best seen in Figs. 1 and 4. The large number of the notches 11'in the quadrant 11, provides a. relatively broad range of adjustment forthe plow, in a vertica plane, for regulating the depth of the plowing.The lever 12 and the links 13 and 14 also afford a ready and convenientmeans for lifting the plow clear of the earth, for facilitating theturning of the vehicle, as well as the movin of the same from place toplace when the p ow is idle. To further hold the Plow 9 and the beam 9'from too free lateral movement, we provide a tie 15, which is pivotallyconnected to the beam 9', and also to a link 16, which is pivotallyconnected to the flange 3 of the crankcase 3 (see Figs. 1, 2 and 5). Thedisposition and arrangement of the tie 15 and the link 16 are such that,the low and beam may be moved vertically, to t e extent shown in Figs.2, 4 and 5. But the said parts tend to prevent the lateral swaying andstraining of the plow and beam, which is the end sought. The forward endof the beam 9', in the present case, is adjustably disposed and heldbetween similar parallel upright members 17' and 17 of a clevis 17,whose lower ends are clamped to the front axle 6, by an suitable means.The members 17 and 1 are correspondingly perforated at frequentintervals as shown, for varying the aforesaid adjustment of the beamrelatlvely to the axle 6'. The clevis 17 is also connected to the beam,at a point intermediate the axle 6' and the link 13, by a pair of links18, the latter being pivotally attached to the beam by a bolt 18'. Bythe provision of the links 18 the beam may be adjusted vertically in theclevis within a certain range by means of pins 17,

as shown by the full and dotted lines in Fi s. 2 and 6. In order tosuitably brace an steady the plow 9, as well as to prevent undue strainswhen the tractor is turned towards the right or' left, we rovide ananchor rod 19, the forward en of which is pivotally connected to thebeam 9, while the rear end of said rod is pivotally secured to the cap 7of the draw-bar 7", by a 100 bracket 19, which is held.in place by bo ts19:. The pivotal nature of the brace 19 allows the plow 9 to be freelyraised and lowered, as indicated by the full and dotted lines in Fig. 2.The brace 19 co-operates with the braces 14", 15 and 16 for reventingthe lateral swaying or rocking o the low and its beam, and tends torestrict all ori-' zontal movements of" the plow to those of the body ofthe tractor and the rear truck rather than to the more pronouncedpivotal actions of the forward truck, which may be effected during theturning movements, while the plow is performin its work, as shown -b thefull lines at t e bottom of Fig. 2. y the foregoing construction andarrangement of the parts the tortuous furrows cut by the plow 9 will besubstantially the same breadth as the straight furrows. This not onlytends to reduce the power requirements of the motor and lessens theconsumption of fuel, and the general wear and tear of the tractor andrelated parts, but also effects the more even and perfect plowin of afield. .Our attachment when proper y constructed and applied, enablesthe driver of the tractor to readil and quickly adjust the plow for deepor s allow plowing, in addition to giving him com lete control of all ofthe working parts 0 the tractor.

Having thus described our invention, what we claim, is-
